First Review: "Sad and desperate" ?

The 'preview' performances of The Farnsworth Invention began their month-long run on Broadway last night, and at least one audience member had the  presence of mind to seek out more information on the web, posting this comment on  YouTube:

"Sad and desperate?" Indeed.... how sad is it that this is the impression that people would come away from the theater with?
